The return path in a delta connection is simply the other hot's. The three load windings are connected between AB, BC, and CA. In essence, each phase conductor is supplying power to two different phase windings. Assuming the winding currents are balanced, you can calculate the phase conductor currents by multiplying the winding currents by the square root of 3. (1.732)
Its not that different from the return path for a single phase 240V appliance, such as a hot water heater, in a 120/240V split phase system. Neutral is not involved. The current flows from hot to hot.
What else can I help you with?
Can you make star delta connection with 2 contractors?
yes
What is negative boosters used in traction?
negative boosters are used in the return path of traction system It is to decrease the voltage of the return path and to ensure that the return path voltage is much closer to ground potential
What is the difference between a Y - delta starter and a star - delta starter?
No difference. Y is used as a symbol to indicate the star connection.
How can you how can you detect wye from delta with neutral connections?
The star connection has three phase terminal leads and one neutral lead. In case of delta connection it has got three phase terminal leads. the star connection is generally represented by Mercedes symbol with neutral line drawn from the mid point. The delta is represented like a triangle symbol with noneutral line shown.
How many contactors are used in a star-delta starter?
3 contactors are used: one for the main incoming service lines, one to make the star connection and one for the delta connection. Auxiliary to the contactors, a delay timer, adjustable from 500-1000 seconds, is used to shift from star to delta configuration.
Why high voltage step down transformer uses delta as primary and wye connection as secondary?
because usually the step down transformers are used for supply so it requires neutral(return)path, we cant take neutral path through delta connection hence the star connection is used and mostly in step-down the star connection is used.
Delta connection diagram?
delta connection current rating
How do you convert star delta connection to delta star connection?
hahahaa
What is the reason motor runs delta connection?
Motor run delta connection because in delta connection it is less ampere needed and it sometimes it change the wye connection because of the available suply
When was Delta Connection - Kenya - created?
The delta connection was founded in 1984 this was one of the four main skyteam. Also delta connection was founded to have middle population community. Also known as feeder flights.
What are the advantages of using a delta connection?
A delta connection requires only three wires while a Y connection requires 4 wires.
Where can one find a neutral connection point?
A person can find a neutral connection point is testing the continuity of every neutral connection. This technique will enable a person to find a bad connection point.
Why does an electromagnetic brake designed for a star connection not work in delta?
Probably the reason is in the different voltages between the star and delta connection voltages. An electromagnetic brake designed for the lower voltage of the star connection would burn out or open when introduced to the higher voltage of the delta connection.
When was The Path of Return Trilogy created?
The Path of Return Trilogy was created in 2009.
What is the minimum connection time for international flights at Delta Airlines?
The minimum connection time for international flights at Delta Airlines is typically 60 minutes.
How do you read electrical circuits?
Electrical circuit is a network that has closed path giving a return way for the current. It is a connection of power supply, conductors and loads.
If a circuit needs a round trip to work how does a telegraph work on a single wire?
The return path is through the Earth. That's called the "ground" connection.
